How do you calculate mean?

add up the numbers and divide by the total numbers you have

put the numbers in order and divide the two middle numbers

subtract the minimum from the maximum

put the numbers in order and find the middle number

When should you use the mean?

If your data set does not have outliers and you are looking for the average.

If your data set has outliers and you are looking for the average.

If you are looking for the middle number.

If you are looking for the range.

Summarize numeric data with numerical summaries, including the mean and median (measures of center) and the range and interquartile range (IQR) (measures of spread), and use these summaries to describe the center, spread, and shape of the data distribution 6.12(D) summarize categorical data with numerical and graphical summaries, including the mode, the percent of values in each category (relative frequency table), and the percent bar graph, and use these summaries to describe the data distribution

Make three questions based on the passage:"The International Labor Organization says the number of people without jobs is increasing. In its latest update on global employment trends, the agency says projections of the number of unemployed people this year range from 210 million to nearly 240 million people. The report warns that 200 million poor workers are at risk of joining the ranks of people living on less than 2 dollars per day in the past three years. The director general of the International Labor Organization Juan Somavia notes that some countries have taken measures to address the effects of the global crisis. However, he points out that many countries have not done so. And based on past experiences, it takes four to five years after economic recovery for unemployment to return to pre-crisis levels. Mr. Somavia says the International Labor Organization is proposing a global jobs' agreement to deal with unemployment. “Its key objective is to place the center of recovery efforts—measures that would generate high levels of employment and provide basic social protection for the most vulnerable."The International Labor Organization says the number of people without jobs is increasing.

7.018 Safe Injection Practices (Refer to 7.07 Safe Injection Policy) Environment of Care: Active participation with all identified projects to assess compliance with infection control standards. . Surveillance, Control, and Reporting includes: Baseline information about the frequency and type of nosocomial infections. Identification of patients and/or staff with communicable or potentially communicable infections. Patients identified with a communicable disease will be isolated from other patients in the facility or, if this is not possible, they will be transferred to a local hospital for care or rescheduled. Identification of clusters of microorganisms or significant deviations from endemic level. Reporting to committees and outside agencies, when required. Investigation of infections as needed. Immediate implementation of corrective and preventive measures that result in improvements. The Infection Control nurse or designated staff member will perform facility audits and report results to the QI committee and Board of Managers. EVALUATION Evaluation and improvement of the infection prevention and control activities are important steps in the Center’s efforts to control and prevent infection. Infection prevention and control practices should become a routine part of the care, treatment, or services the center provides to patients. Patients expect and deserve hygienic and safe care even if their contact with the Center does not extend beyond a single visit. Continuous review of the goals, activities, and outcomes of the Center’s initiative are therefore followed by improvement activities that are realistic in expectation and, above all, effective. Evaluation of the plan shall include but not be limited to: Evaluation of the infection prevention and control activities annually and whenever risks significantly change. The evaluation includes a review of the following: The infection prevention and control prioritized risks The infection prevention and control goals. Implementation of infection prevention and control Outcomes of infection prevention and control activities. Findings from the evaluation are communicated at least annually to the Quality Management Committee References: http://oneandonlycampaign.org/content/what-are-they-why-follow-them.
